Sara is officially the only reason I'm still watching the programme. It reminds me of BB7, when the only thing keeping me hanging on through the endlessly dull weeks was my support of Aisleyne. She's wonderful - a ray of light in a gloomy house full of nastiness and blandness.
I think recent events could do wonders for her popularity. She's already seen quite a good improvement in the betting overnight. Yesterday evening she was milling around on odds of 50/1 and such, and has quickly improved to 33/1. (Mohamed, Darnell and Kathreya are all starting to drift.

)
Hopefully she'll be able to do what Aisleyne did two years ago - be very low down on the betting table, and then suddenly, in the final week, make a massive leap with a sudden surge of popularity. I think a few more good HL edits could put her in contention for a top 3 spot, at least. She's the only one who deserves it.
Sara vs. Rachel would be my dream final. Sadly it looks like the producers could be pushing for Mikey ("The Blind Guy") to win, with Darnell or possibly Lisa as runner-up.
